Abstract (en)
[origin: WO0161873A1] A wireless telephone (200) has a power supply (102), which supplies power to a counter (104), a processor (106), a wireless modem (108), and a transceiver (110). The transceiver (110) communicates with the outside world through an antenna (112). The processor exchanges signals with a clock-calendar (114). When the telephone is in power-conservation mode, the processor opens a switch (216) between the power supply and the transceiver and modem. A second switch (218) is interposed between the power supply (102) and the processor (106), and is under the control of the counter (204). Thus, in power-conservation mode, only the counter draws power. Power-conservation mode (302) may be exited by external command (304), a signal from the clock-calendar (306), or an attempt to place an outgoing call (308).
